• the tab strips 23.1, 23.2 are deflected laterally outward (see Figures 2d, 3d).
• the bead 14.2 bears against the sealing region 8 under a prestress which is sufficiently high to seal the vessel 2 in a liquid-tight and possibly gas-tight manner.
• the user presses against the outside of the second lever 28.
• the force is applied horizontally and with a component upwards.
• the second lever 28 is pivoted to the lid bottom 13 and the first lever 25 is released with the locking edge 26 of the third locking projection 22.
• Further pressing against the second lever 28 causes the first lever 25 with the top on the lower outer edge of the third locking projection 22 slides up until the locking edge 26 slides over the lower outer edge of the third Rastvor jump 22 and gets free.
• the lid 12 is pivoted to the open position (see Fig. 1).
• the lid 12 by means of a hook-shaped Maschinenzeu tot 30 of a laboratory machine can be opened.
• the tool 30 is set with an angled leg 31 at its lower end under the first lever 25 at.
• the first lever 25 is pivoted up, so that the latching edge 26 is released from the third latching projection 22.
• the lid 12 is folded up by means of the tool 30.
• the lidded vessel 1.2 of FIG. 5 differs from that described above in that at the upper end of the second lever 28, a rib 32 extending in the horizontal direction projects outwardly.
• the second lever 28 by counterpressure of a working cone 33, which is used for clamping a pipette tip to the vessel 2 pivoting bar to cancel the latching of the second latching device 29.
• the rib 32 engages in a circumferential annular groove 34 of the working cone 33 a.
• FIG. 7 to 9 show a third lidded vessel 1.3 with hinge 16 and a fully constantly on the inner wall of the vessel circumferential groove 35 at the lower end of the parking area 7.
• the third lid vessel 1.3 has in contrast to the first lid vessel 1.1 no first latching projection 19th
• the third lidded vessel 1.3 coincides with the first lidding vessel 1.1.
• the upper flank 36 of the groove 35 forms the first latching projection 19 which is engaged by the bead 14.2 in the parking position, as shown in FIG.
• the lower edge 37 of the groove 35 engages under the bead 14.2 and prevents the plug 14 in the parking position unintentionally hineinge deeper into the vessel 2 is suppressed.
• the bead 14.2 sealingly abuts the sealing region 8 in the sealing position.
• FIG. 10 shows a fourth lid vessel 1.4, in which lid 12 and vessel 2 are not connected to one another by a hinge 16.
• the vessel 2 has a conical insertion region 38 on the vessel opening 6 on the inside. Directly below the conical insertion region 38, it has a peripheral groove 35 on the inner circumference, which defines a parking area.
• the groove 35 has a triangular cross section with an upper flank 36 and a lower flank 37.
• the vessel 2 has a circumferential flange 10, the radially projecting radially outwardly from a hollow cylindrical portion 3 of the vessel area forming a locking projection 10.1.
• the lid 12 has a lid bottom and a downwardly projecting plug 14.
• the plug has a bead around the outside at the bottom 14.2.
• a portion of the plug 14 is shown in solid lines in the park position. In this position, the bead 14.2 engages in the groove 35. As a result, an inadvertent emergence of the plug 14 from the vessel 2 or deep res entry of the plug 14 is prevented in the vessel 2. As the bead 14.2 sits with clearance in the groove 35, the bead 14.2 does not relax. Since the sealing area 8 is not overloaded, it also does not relax.
• a lower part of the plug 14 is shown in dash-dotted lines in the sealing position. Since the inner diameter of the vessel 2 is smaller than the outer diameter of the bead 14.2 in the sealing region 8, the bead 14.2 seals against the sealing region 8 in the sealing position. Furthermore, in solid lines, a latching hook 39 of the lid 12 is shown in the sealing position. The latching hook 39 engages under the flange 10. This is also the case with the remaining catch hooks 39, not shown. As a result, the lid 12 is held in the sealing position.
• the vessel 2 can be opened by the locking hooks 39 are bent outwards.
• the lid 12 In the park position, the lid 12 can be held in the groove 36 on the vessel 2 solely by the engagement of the bead 14.2.
